The text alignment for one of the code blocks on the unified limits
admin doc page being off by one causes the rendered code block to be
slightly askew.
This fixes the alignment and also adjusts inconsistencies in code block
text alignment throughout the unified limits docs.

We had a long blip between Xena and now where we didn't changed the libvirt
versions. Now it's time to modify the documentation for it.

TODO: We should also modify the supported distro versions.
This addresses comments from code review to add handling of PCPU during
the migration/copy of limits from the Nova database to Keystone. In
legacy quotas, there is no settable quota limit for PCPU, so the limit
for VCPU is used for PCPU. With unified limits, PCPU will have its own
quota limit, so for the automated migration command, we will simply
create a dedicated limit for PCPU that is the same value as the limit
for VCPU.
On the docs side, this adds more detail about the token authorization
settings needed to use the nova-manage limits migrate_to_unified_limits
CLI command and documents more OSC limit commands like show and delete.

When people transition from three ironic nova-compute processes down
to one process, we need a way to move the ironic nodes, and any
associcated instances, between nova-compute processes.
For saftey, a nova-compute process must first be forced_down via
the API, similar to when using evacaute, before moving the associated
ironic nodes to another nova-compute process. The destination
nova-compute process should ideally not be running, but not forced
down.

On reboot, check the instance volume status on the cinder side.

delete its BDMS data from nova DB and vice versa.
Updated existing test cases to use CinderFixture while rebooting as
reboot calls get_all_attachments

As part of the move to using Ironic shards, we document that the best
practice for scaling Ironic and Nova deployments is to shard Ironic
nodes between nova-compute processes, rather than attempting to
user the peer_list.
Currently, we only allow users to do this using conductor groups.
This works well for those wanting a conductor group per L2 network
domain. But in general, conductor groups per nova-compute are
a very poor trade off in terms of ironic deployment complexity.
Futher patches will look to enable the use of ironic shards,
alongside conductor groups, to more easily shard your ironic nodes
between nova-compute processes.
To avoid confusion, we rename the partition_key configuration
value to conductor_group.

This command aims to help migrate to unified limits quotas by reading
legacy quota limits from the Nova database and calling the Keystone API
to create corresponding unified limits.

This change remvoes the az filter and always enabled
the placement pre-filter. As part of this removal
the config option to control enabling the pre-filter

The AZ filter docs and tests are also removed and an upgrade

The 'force' parameter of os-brick's disconnect_volume() method allows
callers to ignore flushing errors and ensure that devices are being
removed from the host.
We should use force=True when we are going to delete an instance to
avoid leaving leftover devices connected to the compute host which
could then potentially be reused to map to volumes to an instance that
should not have access to those volumes.
We can use force=True even when disconnecting a volume that will not be
deleted on termination because os-brick will always attempt to flush
and disconnect gracefully before forcefully removing devices.

Given 2023.1 is our first SLURP release, we need to clarify the level of

Extend microversion 2.90 to allow FQDNs in the hostname parameter.
Multi-create with --hostname continues to be refused, returning error
400 to the user. This simplifies the code by not needing to handle any
sort of suffix or prefix mangling of the FQDN to handle multiple
instances. No other changes are made - not Neutron integration,
metadata API changes (the FQDN will appear as-is in places where the
hostname currently appears), etc.

This patch adds the following SPICE-related options to the 'spice'
configuration group of a Nova configuration:
- image_compression
- jpeg_compression
- zlib_compression
- playback_compression
- streaming_mode
These configuration options can be used to enable and set the SPICE
compression settings for libvirt (QEMU/KVM) provisioned instances.
Each configuration option is optional and can be set explictly to
configure the associated SPICE compression setting for libvirt. If all
configuration options are not set, then none of the SPICE compression
settings will be configured for libvirt, which corresponds to the
behavior before this change. In this case, the built-in defaults from
the libvirt backend (e.g. QEMU) are used.
Note that those options are only taken into account if SPICE support is
enabled (and the VNC support is disabled).
